Solution Overview

Problem

Current A2P and P2A messaging systems lack secure transmission methods, allowing middlemen to access and misuse sensitive user information, leading to privacy breaches and fraud, as existing solutions rely on single symmetric keys that can be compromised.

Innovation Solution

A communication server system with multiple gateways at enterprise, telecom, and user device levels for encrypting and decrypting messages using public and private key pairs, ensuring that only the intended parties have access to the decryption keys, and dynamically rotating keys for enhanced security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If clear content messages are transmitted through middlemen (gateways, telecom servers), then message delivery is enabled, but user privacy and data security are compromised

Engineering Contradiction:

Improvemessage delivery capabilityVSAvoidprivacy breach and data leakage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The message transmission process is segmented into encryption at source, secure transit through middlemen, and decryption at destination. The message content is separated from the transmission infrastructure, with encryption/decryption handled by endpoint devices rather than the messaging server or intermediate components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces encrypted messages as an intermediary form that allows middlemen (messaging servers, telecom servers, gateways) to forward messages without accessing their content. The encryption acts as a mediator that preserves both deliverability and privacy by making the content inaccessible to intermediate systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If single symmetric key encryption is used for message security, then implementation is simple, but security is compromised if the key is leaked

Engineering Contradiction:

Improveencryption implementation simplicityVSAvoidsecurity against key compromise

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The encryption system is segmented into multiple independent key pairs (one for each user), replacing the single symmetric key approach. Each user has their own public-private key pair, so compromise of one key does not affect security of other communications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from symmetric encryption (same key for encryption and decryption) to asymmetric encryption (different public and private keys). Each user generates their own key pair, creating an asymmetric system where the private key remains secret while the public key enables encryption by others.

Inventive Principle:

Principle #4Asymmetry

AI summary

The present disclosure relates to a communication server and a method for secured transmission of messages from an enterprise server to a telecom server for delivering to end users. The enterprise server comprises a first gateway hosted therein to encrypt and transmit the encrypted messages to the communication server. The communication server comprises a routing unit for routing the encrypted messages from the enterprise server to the user devices via the telecom server. The telecom server comprises a second gateway hosted therein to retrieve the encrypted messages. The user device comprises a third gateway hosted therein to retrieve the encrypted messages from the telecom server in case the decryption is taking place at user device.
